you have a ratio.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that ratio is 2/5 = x/75\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "cross multiply to get 2*75 = 5*x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for x to get x = 2*75/5 = 2*15 = 30\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2 gallons will serve 5 people.
\n" ); document.write( "30 gallons will serve 75 people.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if 2 gallons serve 5 people, then the number of people served per gallon is 5/2 = 2.5.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if 30 gallons serve 75 people, then the number of people served per gallon is 75/30 = 2.5.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the question is how much additional punch is required to serve 75 people.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if 2 gallons serves 5 and 30 gallons serves 75, then an additional (30 - 2 = 28 gallons is required to serve 75.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
